-# ─────────────────────────────────────────────────────────────────────────────
-# release.yml — build all 5 patched-Firefox targets at $0 and publish them as
-# DRAFT GitHub Release assets, named per the wrapper contract (constants.ARCHIVE_NAME).
-# DRAFT on purpose: a human runs the realness gate and only THEN un-drafts + bumps
-# BINARY_VERSION. Nothing auto-ships (issue #14 lesson).
-#
-# PACKAGING (issue #14: dangling symlinks broke 265 downloads — never again):
-#   Linux → cp -aL (dereference ALL symlinks into real files) + rm dev tools +
-#           strip + sanitize + tar at ROOT, then validate_release.py as a HARD
-#           in-pipeline gate (the exact battle-tested script from the source repo).
-#   Win   → mach package; zip the CONTENTS of dist/firefox (clean tree, NOT
-#           dist/bin) so firefox.exe sits at the zip ROOT.
-#   macOS → mach package; ad-hoc codesign the .app; PRESERVE its internal relative
-#           symlinks (a .app legitimately has them — cp -aL would break it); verify
-#           every symlink is relative+internal; tar the bundle. --version self-gate.
-#
-# DRIVE GATE (the firefox-8 catcher): after build, every binary is DRIVEN by
-# Playwright on its native runner (launch via juggler + real page + JS roundtrip,
-# headless, no screenshot → GPU-free, zero proxy). A juggler-less binary renders
-# a screenshot fine but is undrivable — only an actual drive catches that. The
-# proxy realness gate (fppro/webrtc) stays LOCAL — it needs secrets.
-#
-# Trigger: push a tag `firefox-N`, or run manually.  Hybrid runners, all free.

-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [Unreleased]
-
-### Added
-- `timezone="auto"`: the browser timezone is auto-derived from the egress IP. By default (no explicit timezone) it ALWAYS resolves — from the proxy egress when a proxy is set, otherwise from the host's own public IP — so the zone can never disagree with the IP (the classic `timezone_mismatch` signal). An explicit `"Area/City"` is the only way to force a specific zone. On failure: with a proxy the launch raises (no silent host-TZ fallback behind a foreign proxy); without a proxy it falls back to the host TZ so a transient lookup can't break the launch.
-- The egress IP is mapped to its IANA zone with an offline mmdb (`daijro/geoip-all-in-one`). It auto-updates against the upstream weekly rebuild: cached locally, re-checked after `GEOIP_REFRESH_DAYS` (7), older copies pruned, and a stale cache is reused when offline. `STEALTHFOX_GEOIP_MMDB` points at your own `.mmdb` to skip the download.
-- `resolve_session_timezone(timezone, proxy)` and `ensure_geoip_mmdb()` re-exported at the package root (plus `GeoTimezoneError`) so integrations that own their launch can reproduce the resolution.
-- `tests/test_geo.py` (37) + `tests/test_geoip_update.py` (freshness / auto-update / offline fallback) unit tests.
-
-### Changed
-- New runtime dependencies: `requests[socks]` (SOCKS egress lookup), `maxminddb` (mmdb reader), `tzdata` (IANA database for `zoneinfo`, which Windows lacks).
-
-## [0.2.0] - 2026-05-28
-
-### Added
-- Public config helpers in `invisible_playwright.config`: `get_default_stealth_prefs(seed, *, pin, locale, timezone, extra_prefs, humanize, virtual_display)` returns a complete `firefox_user_prefs` dict; `get_default_args()` returns the baseline CLI args list (currently empty). Both also re-exported at the package root.
-- `invisible_playwright.ensure_binary` re-exported at the package root for parity with the `cloakbrowser.download.ensure_binary` integration pattern that downstream projects (Skyvern, Crawlee, agno) already expect.
-- These helpers let third-party fetchers (changedetection.io plugins, Crawlee `BrowserPool` subclasses, agno toolkits) drive `playwright.firefox.launch(executable_path=..., firefox_user_prefs=...)` themselves without depending on the `InvisiblePlaywright` context manager owning the lifecycle.
-- `tests/unit/test_config_public.py`: 14 unit tests covering deterministic seed, locale / timezone / pin / extra_prefs / humanize variations, and round-trip via the public namespace.
-
-### Unchanged
-- `InvisiblePlaywright` context manager surface is identical (backwards compatible).
-- `BINARY_VERSION` stays at `firefox-7`. Python-only release; no new Firefox build.
-
-## [0.1.8] - 2026-05-23
-
-### Fixed
-- [#20](https://github.com/feder-cr/invisible_playwright/issues/20): cross-origin iframes were unreachable from Playwright. `element_handle.content_frame()` returned `None`, `frame.evaluate()` threw cross-origin SOP errors, and `frame_locator(...).click()` timed out even with `force=True`. Root cause: FF150 defaults `fission.webContentIsolationStrategy=1` (`IsolateEverything`), which site-isolates every cross-origin iframe into a separate `webIsolated` content process even when `fission.autostart=False`. The parent's Juggler FrameTree then has a Frame placeholder with no docShell and no URL — every protocol op that needs to enter the iframe fails. Fix: pin `fission.webContentIsolationStrategy=0` (`IsolateNothing`) in the baseline prefs. The setting can be flipped back per session via `extra_prefs={"fission.webContentIsolationStrategy": 1}`.
-
-### Added
-- `tests/test_cross_origin_iframe.py`: 4 unit + 5 e2e regression sentinels for cross-origin iframe interaction. The e2e layer runs entirely offline against two local HTTP servers on `127.0.0.1` (two ports = two SOP origins) and covers `page.frames` URL tracking, `content_frame()`, `frame.evaluate()`, `frame_locator(...).locator(...)`, and end-to-end `dispatch_event("click")` for plain, sandboxed and titled iframes. A future FF upgrade or fingerprint A/B that flips the pref back to `1` will fail the suite before shipping.
-
-### Unchanged
-- `BINARY_VERSION` stays at `firefox-7`. Python-only release; no new Firefox build was needed.
-
-## [0.1.7] - 2026-05-21
-
-### Fixed
-- [#18](https://github.com/feder-cr/invisible_playwright/issues/18): Tab crash when running with `headless=True` on Windows on pages that trigger cross-process navigation. Two separate bugs that only manifested together: (1) the Chromium content sandbox at default level 6 puts content processes on `kAlternateWinstation`, but the wrapper hides the browser window on its own alt-desktop (`CreateDesktop` for headless on Windows). Mismatched desktops → cross-process navigations couldn't reparent windows → content process exits cleanly and Playwright fires `page.on('crash')`. (2) The canvas2d `getImageData` stealth spoof wrote to a read-only mapped `DataSourceSurface`. On GPU-backed canvases that memory is write-protected → segfault during the final `getImageData` at page unload. Wrapper now sets `security.sandbox.content.level=4` in the alt-desktop workaround set, and `firefox-7` ships the source fix that moves the noise to the JS array's writable backing buffer.
-
-### Changed
-- `BINARY_VERSION` bumped from `firefox-5` to `firefox-7`. `firefox-6` was rolled back when its partial fix turned out to be wrong (the iframe-burst hypothesis was a dead end; bisection in the evening found the real two-bug cause documented above).
-
-## [0.1.6] - 2026-05-21

-### Added
-- `profile_dir=` kwarg on `InvisiblePlaywright` (sync + async). When set, the session uses `firefox.launch_persistent_context()` so cookies, localStorage, sessionStorage, extensions, cache and prefs are kept on disk between runs. `__enter__` returns a `BrowserContext` directly: `with InvisiblePlaywright(profile_dir=p) as ctx: ctx.new_page()`. Pair with a stable `seed=` to also pin the fingerprint identity across runs. First run creates the dir; subsequent runs reuse it.
-
-### Fixed
-- `launch_persistent_context(timezone_id="…")` no longer times out at 180s. Root cause: `juggler/content/main.js` calls `docShell.overrideTimezone(...)` on every navigation; the patched Firefox up to firefox-4 didn't expose that IDL method on `nsIDocShell`, so the call threw `TypeError: docShell.overrideTimezone is not a function`. On the non-persistent path the error fired *after* launch and was harmless; on the persistent path it blocked the launch handshake. `firefox-5` ships the C++ method (see `patch.md` section 19); this release removes the firefox-4 era Python workaround that was filtering `locale`/`timezone_id` out of the persistent context kwargs.
-
-### Changed
-- `BINARY_VERSION` bumped from `firefox-4` to `firefox-5`. The Python source delta is JS/Python only; the new Firefox build adds 50 lines of C++ in `docshell/base/nsIDocShell.idl` + `nsDocShell.cpp`.
-
-## [0.1.5] - 2026-05-20
-
-### Fixed
-- [#15](https://github.com/feder-cr/invisible_playwright/pull/15): `python -m invisible_playwright fetch` raised `RuntimeError: no SHA256 for firefox-150.0.1-stealth-linux-x86_64.tar.gz in checksums.txt` for every user because the parser kept the `*` binary-mode prefix that `sha256sum` writes in front of filenames. Now `.lstrip("*")` is applied to the key. Reporter + patch: [@LostBoxArt](https://github.com/LostBoxArt). Unrelated to the `firefox-N` binary; existing caches still work, only first-time fetches were broken.
-
-## [0.1.4] - 2026-05-20
-
-### Fixed
-- [#13](https://github.com/feder-cr/invisible_playwright/issues/13): every page that threw an uncaught JS error (e.g. bunny.net) crashed the Playwright client with `TypeError: Cannot read properties of undefined (reading 'url')`. Root cause: upstream Playwright Juggler added a required `location` field to the `Page.uncaughtError` event in the 2026-05-07 roll ([microsoft/playwright@c8604ec](https://github.com/microsoft/playwright/commit/c8604ecd97)); our fork was carrying the pre-roll schema in every `firefox-N` build. Fix matches upstream — Runtime.js builds the `errorLocation`, PageAgent.js forwards it on both worker and runtime error paths, Protocol.js declares the schema field. Reporter: [@dionorgua](https://github.com/dionorgua).
-
-### Changed
-- `BINARY_VERSION` bumped from `firefox-3` to `firefox-4`. JS-only change inside `chrome/juggler/`; `xul.dll` and `firefox.exe` are byte-identical to `firefox-3`.
-
-## [0.1.3] - 2026-05-19
-
-### Changed
-- `BINARY_VERSION` bumped from `firefox-2` to `firefox-3`. The new archives on both Windows and Linux are built from a clean clone of [feder-cr/invisible_firefox#stealth/150](https://github.com/feder-cr/invisible_firefox/tree/stealth/150) — the consolidated source-of-truth fork (renamed from `feder-cr/firefox`; the companion `feder-cr/firefox-stealth` patches repo was deleted, all patches now live as commits on top of `mozilla-firefox/firefox`).
-- The patched Firefox archive now ships the **proper C++ implementation** of `windowUtils.jugglerSendMouseEvent`, replacing the JS shim from 0.1.2.
-
-### C++ fixes landed in this release
-- **C1+C2**: `setDownloadInterceptor` IDL + cpp (re-landed for FF150).
-- **C4**: 5 `nsIDocShell` stealth attributes (`fileInputInterceptionEnabled`, `overrideHasFocus`, `bypassCSPEnabled`, `forceActiveState`, `disallowBFCache`).
-- **C5**: `LauncherProcessWin.cpp` + `nsWindowsWMain.cpp` juggler-pipe handle inheritance — without this, the Playwright pipe disconnects immediately on launch.
-- **C6**: `juggler-navigation-started-renderer` / `-browser` observer notifications in `nsDocShell.cpp` and `CanonicalBrowsingContext.cpp` — without these, `Page.ready` never fires and `ctx.new_page()` hangs.
-- **C7 (partial)**: storage stub for `nsIDocShell.languageOverride`. Workaround `InvisiblePlaywright(locale="")` recommended until full BC FIELD port lands.
-
-### Verified
-- Both archives built from same source: feder-cr/invisible_firefox commit `68906f1f9c55`.
-- Windows + Linux smoke suite green: launch, `ctx.new_page()`, `page.mouse.{move,down,up,click,wheel}`, `navigator.webdriver=false`, sannysoft 32/33 PASS.
-- SHA256 published in `checksums.txt` on the `firefox-3` release.
-
-### Notes
-- This is the first release with a native Linux build of the patched binary (previous `firefox-3` draft mentioned shipping the Linux firefox-2 archive byte-for-byte; that no longer applies — Linux now has the full C++ patch series).
-
-## [0.1.2] - 2026-05-18
-
-### Changed
-- `BINARY_VERSION` bumped from `firefox-1` to `firefox-2`. The patched Firefox archive on GitHub Releases now contains the JS fix from 0.1.1 (every `page.mouse.*` / `page.click()` / `locator.click()` / `mouse.wheel()` failure on the FF150 binary). Users on 0.1.1 must run `python -m invisible_playwright clear-cache && python -m invisible_playwright fetch` to pick up the new archive.
-
-### Verified
-- Archive integrity tests on both platforms: Windows zip extracted + booted via Playwright (`mouse.move + click + page.click(selector)` all succeed end-to-end), Linux tarball file-level checks (firefox/libxul.so sizes, byte-identity of patched JS files against Windows source). 21/21 assertions pass.
-- SHA256 published in `checksums.txt` on the `firefox-2` release.
-
-## [0.1.1] - 2026-05-18
-
-### Fixed
-- **Critical**: every `page.mouse.*`, `page.click(selector)`, `locator.click()`, `page.hover()`, `mouse.wheel()` failed on the patched Firefox 150 binary with `win.windowUtils.jugglerSendMouseEvent is not a function`. The Juggler JS was porting calls to a Playwright-specific C++ method that was never landed in the FF146→FF150 port; replaced with the Mozilla chrome-scope `win.synthesizeMouseEvent` helper which is present in FF150. Six call sites patched across `juggler/protocol/PageHandler.js` and `juggler/content/PageAgent.js`. Reporter: [@trob9](https://github.com/trob9) — [#9](https://github.com/feder-cr/invisible_playwright/issues/9).
-- `_linkedBrowser.scrollRectIntoViewIfNeeded()` is now guarded at both call sites in `PageHandler.js` (`dispatchMouseEvent` and `dispatchWheelEvent`) — the method is not present on the shipped FF150 `<browser>` element, so the unguarded call threw before the mouse event was dispatched.
-
-### Added
-- `tests/test_mouse.py`: 12-case regression suite covering every patched code path (mouse.move/click/dblclick/right-click, modifiers, locator.click/hover, wheel, manual mousedown+up, off-viewport move, humanize intermediate moves, scroll-and-click on offscreen element). Test cases inspired by `microsoft/playwright-python/tests/async/test_click.py`.
-- Community standards: `CODE_OF_CONDUCT.md`, `CONTRIBUTING.md`, `SECURITY.md`, `.github/ISSUE_TEMPLATE/*`, `.github/PULL_REQUEST_TEMPLATE.md`.
-
-### Notes
-- The Stealthfox humanize Bezier expansion continues to fire intermediate `mousemove` events; the swap to `synthesizeMouseEvent` does not change the human-trajectory behavior (verified by test).
-- The reCAPTCHA v3 score (0.90) and FingerprintPro / CreepJS results documented in the README are unaffected — `synthesizeMouseEvent` is a legitimate Mozilla helper that does not increase the anti-detect surface.
-- A binary refresh of the patched Firefox archive on GitHub Releases is required for users to receive this fix (the Juggler JS is shipped inside the archive). The `BINARY_VERSION` will be bumped to `firefox-2` in that release.
-
-## [0.1.0] - 2026-05-13
-
-### Added
-- Initial public release.
-- `InvisiblePlaywright` sync and async context managers — drop-in replacement for `playwright.sync_api.Browser` / `async_api.Browser`.
-- StealthFox humanize hook: Bezier-curve mouse trajectories enabled by default.
-- `_fpforge` Bayesian fingerprint sampler with ~400 fields per session.
-- CLI: `invisible-playwright fetch | path | version | clear-cache`.
-- Pinnable fingerprint fields via `pin={...}` (see `docs/pinning.md`).
-- SOCKS5 / SOCKS4 / HTTP / HTTPS proxy support with auth.
-- Linux x86_64 and Windows x86_64 binary support.

-## Scope
-
-This repository ships the **Python wrapper** (`invisible_playwright`) around a pre-built patched Firefox. In scope:
-
-- The `InvisiblePlaywright` sync/async API and launcher
-- The fingerprint sampler (`_fpforge`)
-- Binary download/caching, CLI, proxy plumbing
-- Tests, docs, examples, packaging
-
-Out of scope (belongs in `invisible_firefox`):
-
-- Changes to the Firefox C++ source
-- New preferences exposed by the patched binary
-- Canvas / WebGL / WebRTC / font spoofing logic
-
-## Development setup
-
-```bash
-git clone https://github.com/feder-cr/invisible_playwright.git
-cd invisible_playwright
-python -m venv .venv
-source .venv/bin/activate  # Windows: .venv\Scripts\activate
-pip install -e ".[dev]"
-python -m invisible_playwright fetch   # download the patched Firefox binary
-```
-
-Requires Python 3.11+ and one of: Windows x86_64, Linux x86_64.
-
-## Running tests
-
-```bash
-pytest                # unit + integration (default — fast)
-pytest -m e2e         # end-to-end, requires the patched binary

+## Results
 
+These are the "best" outcomes observed across independent runs on residential proxies. 
+
+### Google reCAPTCHA v3 - **0.90 / 1.0**
+
+Top-tier score. Google classifies the session as "very likely a human". Most anti-detect stacks plateau around 0.3-0.7.
+
+![reCAPTCHA score 0.90](docs/screenshots/recaptcha_score.png)
+
+### Fingerprint Pro - **bot: not detected, VPN: false, tampering: false, dev tools: not detected**
+
+FingerprintJS Pro's full Smart Signals battery flips every flag to "Not detected". Browser correctly identified as Firefox 150 on Windows 10. Confidence score 0.9.
+
+![FingerprintPro not detected](docs/screenshots/fingerprintpro.png)
+
+### CreepJS - **0 lies**, fingerprint is internally coherent
+
+No contradictions between headless hints, spoofed values, and real rendering output. That "0 lies" is what kills most anti-detect browsers: one inconsistency (e.g. Chrome UA + Firefox WebGL) and the trust score collapses.
+
+![CreepJS 0 lies](docs/screenshots/creepjs.png)
+
+### BrowserLeaks WebRTC - **no public IP leak**
+
+WebRTC srflx address is the proxy egress IP; host candidates are private LAN. The real public IP never leaks via STUN, even on pages that configure their own ICE servers. Stock Firefox leaks the real local IP via WebRTC mDNS - stealthfox doesn't.
+
+![WebRTC no leaks](docs/screenshots/webrtc.png)
+
+### bot.sannysoft.com - **all checks pass**
+
+Every row green: WebDriver not present, Chrome-only properties absent, plugin/mime/languages arrays coherent, permissions API correct, iframe/source window checks pass.
+

 ## Why it's powerful

-**Most other anti-detect browsers patch Chromium at the JavaScript level** - they override `navigator`, `WebGLRenderingContext.getParameter`, canvas APIs, and so on via injected scripts. This has two fatal problems:
 
 1. **JS patches are detectable.** Anti-bots enumerate native function `.toString()`, check descriptor configurability, compare property enumeration order, watch for prototype mutations. Every patch leaves a fingerprint of its own. CreepJS has an entire battery of "lies detectors" built around this.
-2. **Chromium itself is now suspect.** Residential-proxy bot traffic is overwhelmingly Chromium-based, so detectors weight anything Chromium-shaped as risky by default. Chromium-based forks inherit Chrome's open-source layers (BoringSSL, Blink, V8, ANGLE) cleanly, but they still cannot fully match Chrome in practice: Chrome ships closed-source components on top (Widevine, proprietary codecs, Google Update / Safe Browsing endpoints) that flip detectable JS feature flags and network signals, and forks lag Chrome's release cadence by days to weeks, leaving telltale version-specific behaviours that detectors lock onto.
+2. **Chromium itself is now suspect.** Residential-proxy bot traffic is overwhelmingly Chromium-based, so detectors weight anything Chromium-shaped as risky by default. And the parts that matter (TLS stack, renderer process) are not fully open-source in Chrome proper - forks either inherit all Chromium tells or drift in visible ways.

 ## How it compares
 
-**CloakBrowser** ships a similar pitch for Chromium, but its binary is **closed source** (the source-level patches are not published, you only get the compiled output), and it still hits the Chromium reCAPTCHA ceiling. The commercial anti-detect browsers (**Multilogin**, **GoLogin**, AdsPower, Dolphin, Kameleo) are paid SaaS that overlay JS-layer spoofing on a patched Chromium. Managed profiles are nice but raw detection bypass sits below both Camoufox and us.

-invisible_playwright takes a different angle than the major Firefox-hardening projects but stands on their shoulders:
-
-- **[arkenfox/user.js](https://github.com/arkenfox/user.js)** - the canonical Firefox configuration for privacy/security hardening via prefs. Reading arkenfox is how you understand which `user.js` knobs matter; invisible_playwright goes further by patching the C++ source where prefs alone are insufficient (Canvas noise, WebGL parameter overrides, font whitelisting, WebRTC IP swap, DevTools detection bypass).
-- **[LibreWolf](https://librewolf.net)** - a Firefox fork bundled with sensible privacy defaults. Same audience, different distribution model: LibreWolf ships a configured Firefox binary, invisible_playwright ships source patches + a wrapper for automation.
-- **[Camoufox](https://github.com/daijro/camoufox)** - the most well-known open-source anti-detect Firefox project. We share design goals on the fingerprint-spoofing side; the implementation approach differs (Camoufox patches a wider surface and ships its own fingerprint database, while invisible_playwright sticks closer to vanilla and drives spoofing from a Bayesian sampler).

 **Why `class_tier` is pinnable separately from `renderer`.** They live at different levels of abstraction:
 
-- `class_tier` is a **coarse handle** over the whole Bayesian graph. It gates the distribution of `screen`, `hardware.concurrency`, `webgl.msaa_samples`, and storage quota. Pin `{"gpu.class_tier": "low_end"}` and the sampler returns a *coherent* low-end machine - small screen, 2-4 cores, 4x MSAA - without you having to specify each field.

-"""CI drive gate — the firefox-N catcher.
-
-A raw `firefox --screenshot` proves nothing about automation: a juggler-less
-binary renders a screenshot just fine and ships broken (firefox-8 did exactly
-that). This DRIVES the binary the way users will — Playwright launches it over
-the juggler pipe and exercises real paths.
-
-Two levels (see `--full`):
-
-  SMOKE (default — run on ALL 5 legs, on every binary's native runner):
-    launch over juggler-pipe → navigate a real http://127.0.0.1 page → assert a
-    response, the Firefox UA, navigator.webdriver falsy, and a DOM read. This is
-    the firefox-8 catcher (a juggler-less binary throws TargetClosedError on
-    launch) plus a base stealth + drivability check. It is intentionally LIGHT:
-    the free hosted runners — windows-latest especially — are content-process
-    unstable under a heavy headless interaction sequence (clicks/moves cascade
-    into "context destroyed" / selector-timeout / eval-CSP), so the gate that
-    must be GREEN on every leg stays minimal and reliable.
-
-  FULL (`--full` — run on the historically-reliable Linux leg):
-    SMOKE plus mouse + keyboard input (firefox-2 / issue #9:
-    jugglerSendMouseEvent/synthesizeMouseEvent), canvas determinism (stealth
-    seed must be per-session), and navigator-surface tells. The interaction code
-    is platform-identical JS (it lives in omni.ja), so exercising it on one
-    reliable leg catches a regression for ALL platforms; win interaction is
-    additionally covered by local pre-release testing.
-
-NOT covered here: WebGL determinism (needs SWGL, false-fails headless) and the
-faithful cross-origin iframe test (issue #20) — both live in the local realness
-gate. All checks here are headless, no screenshot (GPU-free), loopback-only
-(no external network / proxy / secrets) → safe in public CI.
-
-Robustness: a real loopback HTTP page (NOT data: / about:blank — those get
-re-normalized / carry an eval-blocking CSP), arrow-function evaluates (never
-eval'd), and up to 2 retries on transient context-destroyed/detached/timeout.
-A genuinely broken binary fails ALL attempts → the gate fails.
-
-Usage:  python ci_drive_gate.py <firefox-binary> [--full]
-Exit 0 + "DRIVE GATE OK ..." on success; non-zero with a reason on failure.

-"""Run the FULL e2e suite (every test that opens the browser) against a binary.
-
-The 127 ``@pytest.mark.e2e`` tests are excluded from the default `pytest` run
-(`addopts = -m 'not slow and not e2e'`) because they need a real Firefox binary
-and a display, and they skip themselves when no binary is available. That makes
-them easy to forget — and "we can't afford for something to not work". This is
-the gate that runs them all, deliberately, against a chosen binary.
-
-It is the MANDATORY pre-release e2e gate: run it green against the freshly-built
-release binary BEFORE un-drafting a firefox-N (alongside the fppro + WebRTC
-realness gates). It is NOT in the public CI drive-gate — the hosted runners are
-content-process unstable under a heavy headless interaction sequence (see
-70-known-bugs / 60-ci-release-pipeline); this runs locally on reliable hardware.
-
-Flake-resilience: under full-suite load a couple of interaction tests (dblclick,
-hover/mouseenter) can flake even though they pass 3/3 in isolation, so failures
-are reran up to twice on the known transient signatures. A genuinely broken
-binary fails all attempts. The webrtc e2e fake a TCP-only SOCKS locally (no
-proxy/secrets), so the whole suite is offline.
-
-Usage:

-"""Regression tests for cross-origin / cross-process iframe interaction.
-
-History: wrapper repo issue #20 reported that a third-party cookie
-consent iframe was completely unreachable from Playwright in 0.1.7 —
-``element_handle.content_frame()`` returned ``None``, ``frame.evaluate()``
-threw cross-origin SOP errors, and ``frame_locator().click()`` timed
-out.
-
-Root cause was a missing pref. FF150 ships with
-``fission.webContentIsolationStrategy=1`` (IsolateEverything), which
-site-isolates cross-origin iframes into separate webIsolated content
-processes even when ``fission.autostart=False``. The Juggler code paths
-inherited from the FF146 era assume same-process iframes. The wrapper's
-``_BASELINE`` now pins the pref to 0 (IsolateNothing).
-
-These tests exist so a future Firefox upgrade or a fingerprint A/B
-that flips this pref by accident cannot ship without a red CI signal.
-
-Layers:
-  * ``unit`` — ``_BASELINE`` contains the pref with the right value. No browser.
-  * ``e2e``  — launch the real binary against a LOCAL HTTP harness on
-              ``127.0.0.1`` (two ports = two SOP origins) and verify the
-              four protocol operations that regressed: frame URL tracking,
-              ``handle.content_frame()``, ``frame.evaluate()``, and
-              ``frame_locator(...).locator(...)`` element resolution.
-
-The e2e tests run entirely offline. They never call out to a real site;
-the cross-origin shape is reproduced with two local HTTP servers on
-random free ports.

-"""End-to-end release tests.
-
-These exercise the FULL user install path against the LIVE GitHub release.
-They are slow (download a ~110 MB binary, launch Firefox) and require network
-access — marked `e2e` so they're excluded from the default suite. Run them
-BEFORE announcing a release:
-
-    pytest tests/test_release_e2e.py -m e2e -v
-
-Or to target a specific git revision (default is current HEAD on origin/main):
-
-    INVPW_E2E_REV=v0.1.5 pytest tests/test_release_e2e.py -m e2e -v
-
-What each test verifies and why it exists:
-
-  test_clean_install_from_git_main:
-    Spawns a fresh venv and pip-installs the wrapper from git HEAD. Confirms
-    the package has no broken metadata, missing deps, or import errors in a
-    pristine environment. Catches the "works on my machine because I already
-    have the dev deps" class of bug.
-
-  test_fetch_against_live_release:
-    After the install, runs `python -m invisible_playwright fetch --force`,
-    which downloads the live tarball + checksums.txt for the pinned
-    BINARY_VERSION from the production GitHub release. This is THE test that
-    would have caught LostBoxArt's #15 — the checksums.txt parser bug only
-    manifested against the real binary-mode format the release ships, not
-    against unit-test mocks.
-
-  test_version_command_after_fetch:
-    Confirms `python -m invisible_playwright --version` resolves the binary
-    and reports the expected `firefox-N` tag. Sanity check that the binary
-    landed in the cache and the wrapper can find it.
-
-  test_playwright_launch_against_real_site (linux-only by default):
-    Launches the patched Firefox under the wrapper, navigates to a stable
-    public URL, and reads a known DOM property. This is the full stack:
-    wrapper init → Firefox launch → Juggler handshake → page.goto →
-    page.evaluate. If anything along the way regresses (Juggler protocol
-    schema drift, prefs typo, sandbox issue, …) this fails loudly.
-
-The tests use a temp cache dir per run (env var
-`INVISIBLE_PLAYWRIGHT_CACHE_DIR`) so they never poison the developer's real
-cache and never get false positives from a previously-cached binary.
